2024 CADILLAC LYRIQ CHARGING PROBLEM FIXED SOFTWARE UPDATE

EV Channels Review

The reviewer addresses a persistent DC fast charging issue experienced with their 2024 Cadillac LYRIQ after approximately 1500 miles. Initially, the vehicle charged rapidly, exceeding 100 kW even at higher states of charge. However, performance drastically declined, dropping below 100 kW by 30-40% state of charge. Cadillac service updated the battery management system software, which the reviewer was initially skeptical about due to the service center's limited charging infrastructure. During a test at an Electrify America 350 kW charger, the LYRIQ demonstrated significantly improved charging speeds, peaking at 180 kW and holding over 100 kW until 70% state of charge, and maintaining 90-100 kW up to 80%. While the charging curve tapers quickly, the reviewer deems this performance 'livable' and a vast improvement over the previous issue. The reviewer expresses cautious optimism, hoping the fix is permanent and that Cadillac will implement over-the-air updates in the future. The core takeaway is that the software update appears to have resolved the charging problem for now, making the vehicle suitable for road trips.
